Satellites, as here, the Japanese module "Ibuki",
which measures the effect of greenhouse
gas emissions, already use solar energy.
The Ministry of Economy of Japan announced on
Tuesday 1 September, a group of sixteen companies,
including trucks and Mitsubishi Electric Ihi, participating
for four years in an ambitious research program
aimed to create a powerhouse in space.
The research group is responsible for developing
a technology to transmit electricity without wires,
in the form of microwaves.
If the results are satisfactory, Japan plans to put
into orbit a satellite test, covered with solar panels,
which generate one gigawatt of electricity,
enough to power about 300 000 households.
The budget of the operation amounted
to 21 billion dollars.
Outside the atmosphere, which filters a
significant portion of solar radiation, solar panels
have an efficiency much higher than that obtained
on the ground.
They are not dependent on weather conditions.
On several occasions, NASA was also interested
in generating electricity in space,
without any project to succeed.

Le Japon veut créer son énergie dans l'espace
Le ministère de l'économie japonais a annoncé,
mardi 1er septembre, qu'un groupe de seize entreprises,
dont les poids lourds Mitsubishi Electric et Ihi,
participeront durant quatre ans à un ambitieux
programme de recherche ayant pour objectif
de créer une centrale électrique dans l'espace.
une technologie permettant de transmettre
de l'électricité sans câbles, sous la forme
de micro-ondes.
Si les résultats sont satisfaisants, le Japon
projette de mettre en orbite un satellite de test,
couvert de panneaux solaires, qui générerait
un gigawatt d'électricité, soit de quoi alimenter
près de 300 000 foyers.
Le budget de l'opération s'élève
à 21 milliards de dollars.
Hors de l'atmosphère terrestre, qui filtre
une partie importante du rayonnement solaire,
les panneaux photovoltaïque ont un rendement
bien supérieur à celui obtenu au sol.
Ils ne sont pas non plus tributaires
des conditions climatiques.
A plusieurs reprises, la NASA s'est également
intéressée à la production d'électricité
dans l'espace, sans
qu'aucun projet aboutisse.
